I only say that cuz you'll get more answers. BUT, I think for the money, you might be better off getting a WRX and modifying it. But the STi will be out of my price range, so I can't really say. I got my WRX for $25K, the STi will be ~$28K and the EVO-VII will be about $32K. But go test drive a WRX now to gauge it. 30hp isn't that much more and can be gotten easily. Whatever you do, don't test drive an auto - you'll be unimpressed (unless autos are all you have ever driven.)
